Tar from cigarettes can accumulate on fans, causing them to jam and eventually leading to the system overheating. Nicotine is a chemical found in cigarettes but it is not known to cause fan damage. Carbon dioxide is also found in cigarette smoke, but in lower concentrations and is not likely to cause fan damage. Carbon monoxide is also present in cigarette smoke, but it is a gas and doesn't have a direct effect on the fan.
